摘要:
      高压天然气管道泄漏危害和潜在影响区域取决于泄漏模式、气体释放、扩散条件和点燃方式
等。以某城市在役燃气管道为例，针对燃烧和扩散两种情况对天然气管道泄漏的后果影响进行分
析，计算15 cm 孔洞泄漏、管道压力分别为3.5 MPa 和4.0 MPa 工况下的潜在影响区域、喷射火影响
区域及蒸气云扩散影响区域。结果表明：对于15 cm 孔洞泄漏，无论发生何种情况，距离管道200 m
以外均安全 ，可以以此划定警戒区域，制定应急预案。（表2，图1，参5）
Abstract:
Hazards and potential influence areas of high-pressure natural gas pipeline leaks depend on the mode of leak, gas
release, diffusion conditions and ignition methods. Taking the urban gas pipeline in service as an example, impacts of natural gas
pipeline leaks are analyzed based on two cases of combustion and diffusion. potential influence areas and those for jet fire and
vapor cloud diffusion under the condition of 15 cm-hole leak and pipeline pressures of 3.5 MPa and 4.0 MPa are calculated and
represented graphically. The results show that in the case of a 15 cm-hole leak, it is safe more than 200 m from the pipeline at all
events. Warning regions could be defined and emergency plans formulated based on this. (2 Tables, 1 Figure, 5 References)
